APPARATUS FOR DYEING SLIVERS.

SPECIFICATION forming part of Letters Patent No. 791.148, dated May 30,1905.

Application filed October 14, 1904. Serial No. 228,435.

ratus; and Fig. 2 is an enlarged sectional view taken on line a in saidFig. 1, partly in elevation.

My invention relates to improvements upon the apparatus for dyeingslivers for which United States Letters Patent were granted to me widerdate of September 9, 1902, No.

708,808, and like said patented apparatus isdesigned more especially fordyeing wool, the sliver being preferably taken as it is wound into thetops or cheeses about eighteen inches in diameter after having beendelivered from the first gill-box. Although said apparatus is designedmore especially for dyeing wool in the form of tops or cheeses, as abovestated, I do not limit the same thereto, as it may be employed equallyaswell for dyeing any kind of wool or cotton upon stock, such as wasteor yarn or any of the textileproducts, before being woven into thefabrics.

My present invention relates more particularly to the lower part of theapparatus and the method ofconducting the dyeing liquor to the stock tobe dyed, the upper part of the apparatus being substantially the same asin my said patented apparatus, for a detailed description of whichreference is made to said patent.

My improvement consists in arranging a hood A over the central bottomopening B of the inclined floor B of the apparatus, having apacking-ring O on the bottom edge thereof between said hood and floorand a series of liquor-conducting pipes D, connected with the crown ofsaid hood aboutequidistant apart around the central vertical drive-shaftE, which passes down through the hood. Said 5 pipes D extend up and outradially from the crown of hoodA to the bottom inner edge of the usualperforated cans F, and from said point each pipe has two branches D andD the branch D extending up vertically next to the inner side of itsrespective perforated can .E and the branch D extending horizontally tounder the center of said can and connected with thebottom of theusualvertical perforated tube G, which extends up through the center ofthe can. The branch pipes D are each perforated the whole length of theinner sides next to the cans, as is shown by the enlarged view, Fig. 2,for the purpose of discharging the dyeing liquor against theperforated'surfaces of said cans, which cans being rotated slowlyindependent of the high speed imparted to the operating parts of theapparatus, as described in the patent previously referred to, causes theliquor to enter the cans and pass through the stock'contained therein,the centrifugal force caused by said high rate of speed causing theliquor to percolate thoroughly through every part of said stock, andthus evenly dyes the same throughout its entire body.

I find in practice that much better results areobtained bythe use ofconducting-pipes for distributing the dyeing liquor from the bottomreservoir or tank H than by the construction shown and described in myformer patent, having no separate distributing system for eachperforated can in which the stock to be dyed is held. The liquor is moreevenly distributed, and consequently the stock is more evenly dyed,thereby producing a superior grade of material.

Another advantage of my present improvement is that the liquor beingalmost entirely excluded from the lower part of the apparatus the latterturns with less friction than by my previously-patented construction.

By the employment of the hood A, its packing-ring C, and theliquor-conducting pipes, as shown and described, it will be apparentthat when the apparatus is in operation the liquor which lies in thespace below the inclined floor B and under the hood (an opening Bin-said floor admitting it under said hood) is expelled by centrifugalforce through said conductingpipes and thence through the perforatedcans and material contained therein, and said cans having an independentrotary motion the liquor is distributed very uniformly through thematerial with the result previously stated.

The packing-ring G is not designed to. make an absolutely water-tightjoint, but sufficiently so to not permit suflicient liquor to enteraround the lower working parts of the appatus to cause any materialresistance to the proper action thereof by friction. What little liquordoes enter is discharged over the top of the inclined floor B by thecentrifugal force of the apparatus.

In dyeing coarse open stock, which permits the liquor to percolatethrough the same readily, it is not necessary to employ the centralvertical perforated tubes G in the cans, the perforated pipes or tubes Dbeing suflicient to properly distribute the dye liquor in such case, andI therefore reserve the right to use said tubes G or not as required inpractice in connection with my improvement, an advantage of not usingsaid tubes G being that the stock may be more easily applied and removedto and from the cans F, and it is therefore desirable on this accountnot to use them unless absolutely necessary to do so to properly dye thematerial contained therein, as in treating the finer and more compactlywound stock.

The packing-ring O is a desirable but not essential feature, and Itherefore reserve the right to use the same or not, as desired.

Having now described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is-

1. In an apparatus for dyeing yarn-stock in bulk, the combination of thetank, its inclined false bottom, having a central opening; a hoodarranged over said opening; a packing-ring interposed between the loweredge of said hood and the false bottom; a series of liquorconductingpipes, radiating from different points around the dome of said hood;perfo rated pipe branches extending up vertically next to the innersides of the rotary perforated cans which contain the stock to betreated; branches which connect with the bottoms of the central,vertical, perforated tubes in the cans, and said cans and their tubes,substantially as set forth.

2. In an apparatus fordyeing yarn-stock in bulk, the combination of thetank; its inclined false bottom, having a central opening; a hoodarranged over said opening; a series of liquoreonducting pipes,radiating from different points around the dome of said hood; perforatedpipe branches extending up vertically next to the inner sides of therotary,perforated cans which contain the stock to be treated; branchpipes which connect with the bottoms of the central, vertical,perforated tubes in the cans, and said cans and their tubes,substantially as set forth.

3. In an apparatus for dyeing yarn-stock in bulk, the combination of thetank; its inclined false bottom, having a central opening; a hoodarranged over said opening; a packing-ring, interposed between the loweredge of said hood and the false bottom; a series of liquorconduetingpipes, radiating from different points around the dome of said hood;perforated pipe branches extending up vertically next to the inner sidesof the rotary, perforated cans which contain the stock to be treated,and said cans, substantially as set forth.

4. In an apparatus for dyeing yarn-stock in bulk, the combination of thefalse bottom of the tank, having a central opening; a hood arranged oversaid opening, having a series of liquor-conducting pipes radiating fromdifferent points around its dome, with a packingring interposed betweenthe bottom edge of said hood and the aforesaid false bottom,substantially as set forth.
